What happens when electricity is passed through molten sodium chloride?

When current is passed through molten NaCl i.e. sodium chloride, it decomposes into sodium and chlorine gas. Both sodium and chlorine gas move towards the electrode opposite to their own charge and either loses an electron or gains one.

What type of chemical reactions take place when electricity is passed through molten sodium chloride?

Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride; electrolysis of an aqueous solution of sodium chloride yields sodium hydroxide and chlorine gas. Hydrogen and oxygen are produced by the electrolysis of water.

GOOD TO KNOW:  Best answer: Do water pumps need electricity?

When an electric current is passed through molten sodium chloride sodium is deposited at the anode * 1 Point True False?

sodium and chlorine both deposits at the positive electrode .

How does the molten sodium chloride conduct electricity?

Molten salts conduct electricity the same way they do when they are dissolved in water; some of the salt molecules are dissociated into ions, which allows the ions to conduct electricity. The “Downs Cell” capitalizes on this conduction of electricity to produce virtually all of the metallic sodium required by industry.

What can electricity not pass through?

Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth. … Some insulators can become conductors when they are wet.

Why does calcium metal not deposit instead of sodium at the cathode?

Answer: The cell does not produce calcium metal because the electrowinning of sodium occurs at a less negative cathode potential than does the electrowinning of calcium.

When electricity is passed through molten NaCl chlorine gas is collected at?

Sodium is deposited at the positive electrode and chlorine is deposited at the negative electrode.

When electricity is passed through an aqueous solution of sodium chloride chlorine gas is produce at the cathode True or false?

The electrolysis of sodium chloride (NaCl) produces the positive ion, Na+ and negative ions, Cl−. Thus, the positive ion of sodium will be deposited at the negative electrode (cathode) and the chlorine ion will be deposited at the positive electrode (anode).

GOOD TO KNOW:  How fast is an electrical impulse?

When electricity passes through NaCl aqueous solution * A sodium metal is deposited B only chlorine gas is produced C chlorine & hydrogen gases are produced d all of the given are produced?

NaCl (aq) can be reliably electrolysed to produce hydrogen. Hydrogen gas will be seen to bubble up at the cathode, and chlorine gas will bubble at the anode.

Why is chlorine gas a product of NaCl electrolysis?

Since water can be both oxidized and reduced, it competes with the dissolved Na+ and Cl ions. Rather than producing sodium, hydrogen is produced. Electrolysis of aqueous sodium chlorideElectrolysis of aqueous NaCl results in hydrogen and chloride gas. At the anode (A), chloride (Cl-) is oxidized to chlorine.

What happens when electricity is passed through brine solution name the process?

Complete answer: When electricity is passed through brine it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode. Sodium hydroxide solution is also formed near the cathode. ) is the basic solution obtained at last.

Why does sodium chloride have to be molten before it will conduct electricity?

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

Does molten salt conduct?

The ions cannot move to conduct the electric current . But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.
